Abstract
In the present work, three different die shapes have been considered i.e. Third-order polynomial die, Cosine die and Conical die. AL 1100-O is used as the filler material for all the three dies. The material to be extruded was modelled as a perfect plastic material for the non-linear analysis during the finite element simulation. Output from the finite element program included Directional deformation, at different Die Pressure i.e. 800 MPa, 1200 MPa and 1600 MPa. Based on the finite element analysis results the Cosine die is best among all the three-die considered for the study i.e. Cosine Die, Third-order polynomial Die and conical die.
